Transducer Connection
A 30 ft (10m) cable is supplied with the transducer. The trans-
ducer cable may be extended up to a maximum of 60 ft (20 m)
using optional extension cables. For details, see document number
81196,
Transducers for Fishfinders Owner’s Handbook.
The transducer cable connector (and Y-shaped connector, if sup-
plied) has a nut that has been removed to aid installation. To ena-
ble you to complete the installation without cutting the cable,
ensure that any holes you drill are large enough to accept the con-
nector, with the nut removed (approximately 13/16" or 21 mm).
WARNING:
Take care not to pull on the cable. This can damage the
transducer wires.
Before attaching the transducer cable, you will need to attach the
connector nut and split ring. These items, plus a wedge tool, are
included in the transducer packaging.
The transducer cable is attached to the 7 pin male connector
marked
TRANSDUCER
on the connector panel of the DSM250.
How you connect the cable depends on the type of transducer you
have installed:
• Combined depth/speed/temp transducers (‘triducers’) have a 7
pin female connector. Attach the transducer cable connector
directly to the display unit.
• Combined speed/temperature transducers have a 3 pin female
connector that requires the use of an additional Y-shaped cable
(Raymarine part number E66022) to attach to the 7 pin connector
on the display. This Y-cable is included with your speed/tempera-
ture transducer.
Attach the 7 pin female connector on the Y-cable to the sounder
module, and then attach the transducer cable to the 3 pin male
connector on the Y-cable.
• Depth-only transducers have a 7 pin female connector.
Attach the transducer cable connector directly to the sounder
module.
If being installed in conjunction with a speed/temperature trans-
ducer, attach the Y-cable’s 7 pin female connector to the sounder
module, and then attach the transducer cable to the 7 pin male
connector on the Y-cable.
